彩电是声像合一的电器,多年来,彩电设计者在竭力改善画质的同时,也在逐渐改进其伴音质量。各种原先用于音响的专用电路,如等响度、音调均衡、环绕立体声等已被移植到某些彩电电路中。当然,不少厂家为方便用户的理解和使用,把以上功能冠之于“语言模式”、“古典音乐模式”、“打击乐模式”、“超重低音”等等,并把这些用户自己所喜爱模式的控制量转换为数字量存储 Color TV is a combination of audio and video appliances, over the years, color TV designers strive to improve picture quality, but also gradually improve its sound quality.
